Possibly Unhandled Rejection NodeJS Promise Hook

###Unhandled Rejection Tracking

Several promise libraries such as bluebird and when as well as some native promise implementations offer potentially unhandled rejection tracking. This means that the following:

Promise.reject(new Error("err")); // never attach a `catch`

let once = (fns, called) => // fns is an array of functions, called is undefined if first call
  fns.map(orig => function OnceBinded(){
    if(called) return; else called = true;
    return orig(...arguments);
  });
export class Promise {
  constructor(resolver){
    Object.assign(this, {_handlers: [] , _state : State.Pending, _value: null});
    resolver(value => {
      if(this._state !== State.Pending) return;

You walk to your home and you want to share a TipRanks stock page with a friend on your phone, however you forgot your friend's email. You do remember it starts with "Gilad" followed by 4 positive integers whose squares are summed to 101 and are in descending order (what an odd way to remember someone's email) following @tipranks.com. Can you figure out Gilad's email?

Once you figure Gilad's email, send him an email saying you solved the challenge (add your CV for extra credit)!
